Can I upgrade my Bose Wave Series IV radio/cd system to bluetooth to play music from Alexa?
Thank you for posting and welcome to the Bose Community!
If you have an existing Alexa device such as an Echo Dot, you could plug this in directly to your Bose Wave Music system directly with a 3.5mm AUX cable into the AUX port on the Wave.
Let me know if you have any other questions.
